radisys.com 26 Radisys Series — Who Disaggregated My RAN? eBook Chapter 6: Open RAN: Achieving On-par Field Performance In this series focused on the benefits of a disaggregated Open RAN, we have had a chance to see how an open RAN has helped expand the ecosystem and led operators to consider new vendor solutions that meet their needs. Standards have emerged which help ensure increased interoperability. In the last blog post we covered system integration and pre-deployment aspects of disaggregated RAN solutions in detail. In this latest entry to our series, we'll take a look at how disaggregated solutions compare in terms of benchmarking performance. Performance and Deployment Readiness There are a couple of questions that are often brought up: Will an open disaggregated multi-vendor RAN solution perform as good as the traditional (closed) RAN solutions? Do these disaggregated components. as a whole meet the various needs of an operator deployment? The answers to these questions lie in the way open and disaggregated solutions are built. These are of course vast and complex topics. We must take into account the hardware, software and other aspects critical to building a high-performance RAN solution. Let us look at some of the key ingredients of such a solution. The picture to the left illustrates these aspects. For Open RAN solutions to prove that they match up head-to-head with traditional solutions, we need to understand how commercial off-the-shelf (COTS) products can come together to form a complete solution.
